Wizzard Software announced Wednesday that AT&T Natural Voices are now available for Mac OS X v10.3 “Panther” and Mac OS X v10.4 “Tiger.” The voices — replacements for the text to speech voices Apple includes with Mac OS X — are being offered to application developers who want to use better-sounding voices than what Apple includes.
AT&T Natural Voices are available in English, French, German and Spanish. Wizzard Software bills them as “one of the most human-sounding speech synthesis systems in the world.”
The software development kit (SDK) prices for developer start at US$295 per speech “font.”
